HARVESTING-MACHINE.

To u?! 1r]: om it may concern Be it known that I, ISIIAM F. \Vncoxson, a citizen of the United States, residing at Dryden, in the county of I-Iarmonand State of Oklahoma, have invented certain new and useful Improvements in I-larvesting-Machines. of which the following is a specification, reference being had to the accompanying drawings. i

This invention relates to improvements in harvesting machines of that character shown and described in my prior application for Patent Serial No. 789,910, filed September 15. 1913, and has for its primary object to provide certain material improvements in such machines whereby their serviceability and scope of utility in practical use is materially increased.

My invention has for a more particular object to provide improved means for separating the bolls from the cotton and, discharging the same from the machine in its movement across the field.

My invention has for still another object to provide improved means for effectually removing grass, leaves or other refuse matter from the cotton before it is finally discharged from the machine. i 1

'ith the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain (fUflStl'flCtlOIlS, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a vertical longitudinal section through a cotton harvesting machine embodying the invention in its preferred form; Fig. 2 is a top plan view thereof; Fig. 3 is an enlarged fragmentary section illustrating f j upper and lower ends respectively of the obliquely disposed intermediate portions of the frame members 12, and an endless apron the driving gearing; Fig. 4 is a detail fragmentary bottom plan view.

Referring in detail to the drawings, 5 designates the supporting shaft or axle upon the opposite ends of which the traction or ground wheels 6 are loosely mounted. These wheels which may be of any ordinary or approved construction are provided with pawls 7 adapted for engagement with suitable ratchets 8 fixed to the shaft 5, whereby said shaft is caused to rotate upon the forward movement of the machine.

loosely mounted adjacent their rear ends.-

These parallel bars are connected by a series of transverse bars 10. To one of the latter bars, the rear end of the draft tongue 11 is pivotally connected. Between the longitudinal bars 9 the side members 12 of a frame are arranged, each of said side members having obliquely disposed portions and longitudinally extending end portions asshown. The obliquely disposed portions of these side members are provided with spaced slots 13 to receive bolts 11 mounted in the bars 9, and upon the outer ends of said bolts suitable clamping nuts 15 are threaded to clamp the side members 12 in their adjusted positions between the longitudinal bars. The frame members 12 have their horizontal rearwardly extending end portions connected by the transverse bars 16 and a base or floor 17 is arranged between the obliquely disposed portions of said side members at their lower edges.

Between the forward ends of the members 12, the transversely disposed cylinder 18 is mounted, said cylinder being preferably adjustable vertically in the manner disclosed in my prior application hereinbefore referred to. This, cylinder is provided upon its periphery with a plurality of teeth 19 which are adapted to coi'iperate with the series of 'break open the cotton bolls.

teeth 21 on the transverse bar 20 to cut or The forward said tines being fixed at their rear ends in the bar 20. A plurality of spaced transverse rods 24 connect the lower edges of the frame members 12 in advance of the floor 17.

Rollers 25 and 26 are mounted between the or conveyer 27 traverses these rollers. This apron is preferabl provided with a plurality of spaced toot carrying bars 28 for a purpose which will be later referred to. w

The cotton is discharged from the upper end of the apron u on a plate 29, one end of which is fixed to t e upper end of the floor 17 and the other end thereof suitably secured to a bar 30 which is provided with 116 is mounted between the members 12.

' cratcd. Upon the other end of the shaf upstanding teeth 31. S2 designates a roller mounted immediately above the bar 30 upon a shaft 83. This roller is provided with the peripheral teeth 31 which are adapted to move between the teeth upon the bar 30. A plurality of parallel longitudinal spaced rods 85 are secured at their ends to the bar 30 and to the rear transverse barlG respec-- This roller is also provided with peripheral teeth 40. Below the rods 35 and also rearwardly of the saws 37 a rotatable brush 41 A transversely disposed casing or trough 42 mounted upon the bar 16 and in the same the spiral conveycr is arranged. This convcycr at one of its ends discharges into a chute 14 mounted upon one of the side members 12. An inclined cotton discharge chute 41 is secured to the lower edges of the-members 12 and is adapted to discharge the cotton from the machine into the body of a suitable vehicle indicated at which is connected in any suitable manner to the rear end of the machine.

Upon one end of the wheel shaft 5 a sprocket wheel 46 is secured and is connected by a chain 47 to a similar sprocket wheel 48 secured upon one end of the shaft of the cylinder 18. Jpon the other end of this cylinder shaft a gear wheel .45) is fixed which n'ieshes with the gear 50 secured upon the shaft of the lower apron roller 26. Upon the other end of the wheel shaft a sprocket wheel 51 is secured and is connected by the chain to a sprocket piir ion fixed upon one end of the shaft upon which the toothed roller 32 is secured This shaft is also provided with a second sprocket pinion 54 which is connected by the chain to a sprocket pinion 56 upon one end of the shaft of the spiral conveyer 13. This chain also engages a sprocket wheel 57 secured upon one end of the shaft 39 of the roller 38 whereby said roller is opa g ar wheel 58 is secured and meshes with a similar gear wheel 59 fixed upon one end i of the saw blade shaft 36.

This latter car in turn meshes with the pinion (30 secured upon one end of the shaft of the brush 41.

The inclination. of the frame of the mabeing provided with the usual spring pressed locking dogs 63 for engagement with the teeth of said rack. The pivot rod (31 of the lever extends upon opposite sides of the rack and to the ends thereof the arms (35 are fixed at one of their ends. The other ends of these arms are pivotally connected to the upper ends of the links co, the lower ends of which are pivotally connected to the extensions 22 of the side members 12. The operatofis seat (37 is mounted upon the rear end of the tongue 11. It will be readily understood that by simply shifting this lever, the frame may be oscillated upon the wheel shaft and the tines 23 raised or lowered to the proper elevation with respect to the ground as may be desired.

Having now specifically described the con struction and arrangement of the several parts constituting my improved harvesting machine. the operation thereof will be understood as follows: In the movement of the machine across the field, the cotton stalks are directed by the forwardly extending tines 23 against the rotating cylinder 18. The. teeth 19 of this cylinder strip the stalks of their pods and carry the pods rearwardly over the toothed bar 20. The teeth of this bar cooperating with the teeth 19 of the cylinder cut or break open the cotton bolls. Short rearwardly projecting rods 20 fixed in the rail edge of the bar 20 direct the cotton upon the upper stretch of the apron 27. Any cotton which may fall between the paced rods 20 will lodge upon the transverse rods 24 disposed beneath the lower end of the apron and be caught by the teeth upon the apron slats 28 in the movement of the apron around the lower roller 26, The cotton is *arricd upwardly by the apron and discharged upon the downwardly inclined plate 29 fixed to the upper end of the door 17. it is now caught by the teeth of the cylindcr 3i and forced between the teeth 31 by which the complete opening of the bolls is assured, The saws 37 now catch the cotton and pull the same downwardly between the parallel rods 35 and completely separate the same from the bolls. The toothed cylinde" 38 directs the bolls rearwardly over said rods into the trough 12 of the spiral conveycr 13. This 'convever directs the bolls transversely and discharges the same from the machine into the downwardly inclined chute H. The revolving brush ll removes the cotton from the teeth of the saw blades 37. the same falling; upon the downwardly inclined discharge chute 11- by which it is discharged into the trailing vehicle 45.

From the above it is believed that the construction and n'ianner of operation of my invention will be clearly and fully understood.

The machine is comparatively simple and inexpensive n1 construction and highly satisfactory and serviceable in practical use.

It will be seen that the cotton bolls are separated from the cotton after the same has been stripped from the stalks and the cotton is delivered from the machine practically free of refuse matter.

It will, of course, be apparent that in putting my invention into practical use, it may be found desirable to make many changes in the form, proportions and arrangement of the several elements above referred to and 1,
